Quick release assembly for an electronic device

ABSTRACT

A quick release assembly is provided to enable a user to easily attach and detach electronic equipment such as a flat panel monitor to an extension arm or other mounting device. One embodiment of the quick release assembly includes an adapter plate for connecting to the electronic equipment, a connecting plate for securing to the mounting device, and a release plate disposed between the adapter plate and the connecting plate. When fully assembled, the user can press a release mechanism on the release plate to disengage the release plate and the connecting plate from the adapter unit. After the release mechanism is pressed, the connecting plate can be slid off of the adapter plate. Unlike conventional devices, it is not necessary to remove or loosen hard to reach fasteners in order to disconnect the electronic device from the mounting device.

BACKGROUND OF THE INVENTION

The present invention relates to a device for use in connecting electronic devices. More particularly, the present invention relates to a quick release assembly that enables a user to attach and detach an electronic device such as a flat panel display from a mounting apparatus.

In the past people have placed video monitors and other electronic equipment on desks, tabletops, or upon other equipment such as personal computers or workstations. One drawback to these configurations is the reduction in available workspace taken up by the equipment. Another drawback is the inability to place the equipment in a desired location. A further drawback is the potential for eye strain, neck strain and/or a cumulative trauma disorder such as carpel tunnel syndrome from poor placement of devices such as monitors and keyboards.

Different solutions have been provided in order to overcome these obstacles. For example, in one solution, a monitor stand or printer stand elevates the apparatus over other equipment on a desk. While this may free up workspace, it often places the equipment in an undesirable location. Another solution employs a mechanical extension arm to support the monitor. Extension arms free up workspace and allow users to place the equipment where it is wanted. One such extension arm is shown and described in U.S. Pat. No. 6,478,274, entitled “Arm Apparatus for Mounting Electronic Devices,” which is fully incorporated by reference herein. Another type of extension arm is shown and described in U.S. Pat. No. 6,409,134, entitled “Arm Apparatus For Mounting Electronic Devices With Cable Management System,” which is fully incorporated by reference herein.

It is often desirable to obtain additional freedom of movement beyond that provided by the extension arm. A tilting device can be used to accomplish this goal. The tilting device is placed between the extension arm and the equipment, allowing the equipment to rotate about one or more axes. One such tilting device is shown and described in U.S. Pat. No. 6,505,988, entitled “Tilter for Positioning Electronic Devices,” which is fully incorporated by reference herein.

While such tilter devices are very useful for positioning the equipment in a desired position, it may be difficult to rapidly detach the equipment from the tilting device and extension arm assembly. For example, a monitor may be secured to the tilting device by multiple screws. It might take several minutes to disassemble all of the screws, detach the monitor, and then attach a new monitor. In many businesses, such as brokerage firms and other investment concerns, users require ongoing access to a working display unit. Disruptions, even those as short as a few minutes, can seriously impacting users' abilities to perform their jobs. Thus, a quick release mechanism is needed to rapidly swap out a broken monitor for a working monitor. Furthermore, in order to detach the monitor without dropping it, the user needs to be very careful when removing the screws from a conventional tilting device so that the monitor does not suddenly detach and fall to the floor. It may be difficult to the access the screws, as there may not be much clearance between the monitor and the tilting device. Therefore, a need exists for a quick release mechanism to address these and other concerns.

DETAILED DESCRIPTION

The aspects, features and advantages of the present invention will be appreciated when considered with reference to the following description of preferred embodiments and accompanying figures. In describing the preferred embodiments of the invention illustrated in the figures, specific terminology will be used for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each term selected includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.

FIG. 1 illustrates an extension arm 100 that can be connected at one end to a mounting assembly (not shown) and attached to a tilting device 200 at the other end. The mounting assembly may be of any desired configuration, and may be affixed to a piece of furniture such as a desk, a wall such as a slat wall, a section of an office cubicle, etc. The tilting device 200 can be connected to an electronic device 300 such as a flat panel monitor. A cable 302 is connected to the electronic device 300 at one end, and has a plug or other connector 304 at the other end. While the electronic device 300 is described below as a flat panel monitor or other video monitor, the invention is not limited to use with such devices, and may be used with a wide variety of equipment, including non-powered equipment.

The extension arm 100 may be a conventional extension arm or any other suitable mounting device. Preferably, the extension arm 100 is one of the types fully described in above-referenced U.S. Pat. Nos. 6,409,134 and 6,478,274. As shown in FIG. 1, the extension arm 100 may include a first endcap 102, an arm 104, a second endcap 108 and a forearm extension 110.

The first endcap 102 includes a housing attached to one end of the arm 104 by, for example, pins. A shaft 118 or other connection device is adapted for connection to the mounting assembly. The shaft 118 may be integrally molded with an endwall of the housing of the first endcap 102. Alternatively, the shaft 118 may be securely attached to the housing of the first endcap 102. The shaft 118 is preferably integral with the first endcap 102.

The arm 104 is preferably formed of an upper housing 106 a and a lower housing 106 b. The upper housing 106 a and the lower housing 106 b define a chamber therebetween containing, for example, a gas spring (not shown). The gas spring is preferably adjustably mounted at one end within the first endcap 102 and at the other end to, for example, a ball stud mounted within the upper housing 106 a. The cable 302 may be secured within the arm 104 as shown and described in U.S. Pat. No. 6,409,134. Alternatively, the arm 104 may include one or more external cable ties in order to secure the cable 302 of the electronic device 300 supported by the extension arm 100.

The second endcap 108 has a housing attached to the second end of the arm 104 by, for example, pins. A shaft may extend out of the top of the housing of the second endcap 108 and optionally connect to the forearm extension 110. The forearm extension 110 includes a body 114 having an interior channel, as well as a first end 112 and a second end 116. The forearm extension 110 is preferably rotatable about an axis of the first end 112.

The upper housing 106 a, the lower housing 106 b, the first endcap 102 and the second endcap 108 are configured so as to form an adjustable parallelogram. When configured, the housing of the first endcap 102 and the housing of the second endcap 108 point in opposite directions. The shape of the parallelogram is retained by the gas spring within the chamber of the arm 104. Generally, the gas spring is sized so as to have a fixed length until an upward or downward force is exerted at the second endcap 108 that exceeds the gas spring's designed resistance. Thus, the gas spring retains the parallelogram shape when the only force exerted at the second endcap 108 is the weight of the electronic device 300. However, the gas spring permits the parallelogram shape to be adjusted when a user pushes the electronic device 300, which is preferably coupled to the forearm extension 110 by means of the tilting device 200, up or down.

The tilting device 200 can be directly connected to the endcap 108 or to the second end 116 of the forearm extension 110, and is preferably rotatable thereabout. Different tilting devices 200 can be used to tilt, angle, pivot and/or rotate the electronic device 300 in accordance with aspects of the present invention. By way of example only, as seen in FIG. 2, the tilting device 200 may enable the electronic device 300 to rotate or pivot about two axes, namely the X-axis and the Y-axis. An adapter unit 202 connected to the tilting device 200 may rotate or pivot about the Z-axis. The forearm extension 110 preferably has a locking mechanism for restricting movement of the tilting device 200 about the Y-axis. The tilting device 200 may also include a locking mechanism for restricting movement about the X-axis. The locking mechanisms may comprise, for example, a set screw insertable into either a wall of the second end 116 or into a portion of the tilting device 200.

The tilting device 200 may comprise known components, such as those shown and described in aforementioned U.S. Pat. No. 6,505,988. As seen in FIG. 2, an embodiment of the tilting device 200 for use in accordance with the present invention includes a tilter head 204, a tilter mount 206, and a tilter bar 208 coupling the tilter mount 206 to the tilter head 204. The adapter unit 202 couples the electronic device 300 to the tilting device 200.

Examples of the tilting device 200 and the adapter unit 202 are shown in more detail in FIGS. 3( a)-(c). As seen in the rear and side views of FIGS. 3( b) and 3(c), the tilter head 204 preferably includes a base or stem 210 for insertion into the second end 116 of the forearm extension 110 or into the endcap 108.

The post 250 on the release plate 214 is preferably at least partly received in the opening 233 of the adapter plate 212. The pair of arms 258 preferably contact the pair of flat surfaces 242 a,b. At this point, the main body 245 and the arms 258 preferably lie along the same plane.

FIG. 9( b) illustrates the rotating plate 216 after it is coupled to the adapter plate 212 and the release plate 214. When the rotating plate 216 is connected, the release plate 214 is sandwiched between the rotating plate 216 and the adapter plate 212. The bosses 256 on the front side 246 of the release plate 214 are preferably securely received by the receptacles or openings 274 in the rotating plate 216. Alternatively, the front side 246 of the release plate 214 may have receptacles or openings that connect to bosses in the rotating plate 216. In fact, many different types of fastening means are suitable to connect the release plate 214 to the rotating plate 216. The rotating plate should be positioned so that the angled members 278 of the connectors 276 wrap around the second end 238 of the adapter plate 212. The angled members 278 may contact the receptacles or regions 225 (if any) on the front side 218 of the adapter plate 212. The tab(s) 232 on the adapter plate 212 preferably cover the corners of the rotating plate 216 adjacent to the receptacles or openings 274. The tabs 232 help retain the rotating plate 216 in place.

FIGS. 9( c)-(f) illustrate views of the assembled adapter unit 202. FIGS. 10( a)-(c) illustrate the adapter unit 202 releasably connected to the tilter mount 206. Of course, it should be understood that the rotating plate 216 may be riveted to the tilter mount 206 prior to attaching the rotating plate 216 to the release plate 214 and the adapter plate 212. The electronic device 300 may be secured to the adapter plate 212 before or after the whole adapter unit 202 is assembled. The rotating plate 216 permits the release plate 214, the adapter plate 212 and the electronic device 212 to rotate relative to the tilter mount 206.

Once the tilter mount 206 is affixed to the rotating plate 216, the tilter head 204 can be connected to the tilter mount 206 using the tilter bar 208. It should also be understood that the tilter mount 206 may be connected to the tilter head 204 and the tilter bar 208 before or after being riveted or otherwise fastened to the rotating plate 216. After the quick release adapter unit 202 is properly assembled and connected to the tilting device 200 and the electronic device 300, the electronic device preferably becomes adjustable about one or more of the X, Y, and Z-axes as shown in FIG. 2. However, while the rotating plate 216 is described as permitting the electronic device 300 to rotate about the Z-axis, other non-rotating connector plates may be utilized in which the electronic device 300 is not rotatable about the Z-axis. In such cases, the protrusion 270 on the rotating plate 216 is unnecessary, as are the washer channel 292 and the washer 296.

In order to detach the electronic device 300, the user preferably pulls, pushes or otherwise causes the post 250 or other release mechanism to move within the opening 233 of the adapter plate 212 and toward the electronic device 300. This, in turn, causes the main body 245 to deflect or move away from the rotating plate 216. The bosses 256 or other projections of the release plate 214 thus disengage from the holes or recesses 274 of the rotating plate 216. At this point, the rotating plate 216 is at least partly disengaged from the adapter plate 212. If it has not already occurred, the angled members 278 of the connectors 276 are then disengaged from the second end 238 of the adapter plate 212. When the second end 238 of the adapter plate 212 points upward, the rotating plate 216 may be fully removed by sliding it up and off of the adapter plate 212. The electronic device 300 can be placed on a stable surface prior to disengagement in order to avoid potential damage to the electronic device 300.

After detachment of the electronic device 300, the release plate 214 preferably remains coupled to the adapter plate 212. Optionally, the release plate 214 may be detachable from the adapter plate 212. Then the same or a different electronic device 300 may be reattached to an extension arm or other mounting device by securing the rotating plate 216 to the rest of the adapter unit 202 as described above.

While the release plate 214 permits a user to rapidly disengage the rotating plate 216 from the adapter plate 212, there may be situations when it is desirable to prevent inadvertent or unwanted disengagement. For example, in a high traffic environment, one would like to discourage unauthorized personnel from tampering with the equipment. FIG. 11( a) illustrate a security mechanism in the form of a threaded fastener 298 that is preferably receivable by the through-hole 244 in the adapter plate 212. As seen in FIG. 11( b), when the security mechanism is engaged, e.g., when the threaded fastener 298 is screwed into the through-hole 244, it is not possible to slide the rotating plate 216 away from the adapter plate 212 and the release plate 214. While the security mechanism is illustrated as the threaded fastener 298, many other mechanisms may be used, including, but not limited to clips, clasps, hasps, locks, pins, wing nuts, etc. Thus, it becomes difficult for an unauthorized user to quickly release the adapter plate 212 and the monitor or other electronic device 300 from the rotating plate 216 and the tilter mount 206.

It can be seen that the present invention provides a quick release device which allows a user to easily attach and detach electronic equipment to an extension arm or other mounting device. It is not necessary to remove or loosen hard to reach fasteners in order to disconnect the electronic device. In the brokerage firm example given earlier, a defective monitor may be rapidly swapped for a new monitor, permitting the broker to continue trading without adversely affecting his or her performance. The present invention also provides an alternative security mechanism to prevent unauthorized or accidental detachment of the electronic equipment.

Adapter units in accordance with aspects of the present invention may be used with conventional extension arms and tilting devices. New tilting devices, including the tilter mounts described herein, may also be used with the adapter units to provide partial or full rotation of electronic devices about one or more axes.
